This post includes a summary of the White Paper submitted in 2019 to the ESA Voyage 2050 procedure, which was consequently released in EPJ Quantum Technology AEDGE Collaboration et al. We suggest in this White Paper an idea for a space experiment using cold atoms to search for ultra-light dark matter, and to identify gravitational waves in the frequency range in between one of the most sensitive varieties of LISA and the earthbound LIGO/Virgo/KAGRA/ INDIGO experiments. AEDGE will be based upon modern technologies now being developed for earthbound experiments making use of cold atoms, and will benefit from the space experience obtained with, e. G., LISA and cold atom experiments in microgravity.

There is compelling cosmological and astrophysical evidence of dark matter making up 27% of the energy budget of deep space. ^180m Ta is the rarest well-known isotope with the longest-lived meta-stable state whose partial half-life limitations are on the order of 10 ^14 -10 ^16 yr. We explore how strongly interacting dark matter and inelastic dark matter clash with ^180m Ta, causing its de-excitation. The Standard Cosmological Model presumes that more than 85 of matter remains in the type of collisionless and pressureless dark matter. Unstable decomposing dark matter has been recommended in the literature as an expansion to the conventional cool dark matter model. We take into consideration a class of U^’ -prolonged MSSM in which the U^’ balance is damaged by a vacuum cleaner assumption values of four MSSM singlet fields. If the relic thickness of dark matter is saturated just by a neutralino, suitable solutions predict LSP neutralinos formed by the MSSM singlet fields in the mass scales below concerning 600 GeV, while it is feasible to realize MSSM neutralino LSP above these mass ranges. Previous research has revealed that dark matter lacking galaxies such as NGC1052-DF2 can result from tidal stripping. The scattering of light dark matter off thermal electrons inside the Sun generates a quick subcomponent of the dark matter flux that might be obvious in below ground experiments. We discover that big Xenon-based experiments give the best direct limitations for dark matter masses below a couple of MeV, reaching a level of sensitivity to the reliable dark matter charge of ∼ 10 -9 e. Title: Solar representation of dark matter. 2 models that link cozy inflation with dark matter and dark energy are suggested. In the models, a solitary scalar area is accountable for the early expansion of the Universe with the procedure of dissipative cozy rising cost of living, and afterwards acts as both dark matter and dark energy in successful phases.

Conformal and disformal combinings in between a scalar field and matter occur normally generally in scalar-tensor concepts. In a D-brane-like scenario, the scale at which the growth rate improvement happens depends upon the string coupling and the string range. The growth of an enormous black hole will steepen the cool dark matter thickness at the center of a galaxy right into a dense spike, improving the prospects for indirect discovery. We locate that, regardless of the transfer of angular momentum from the opening to the halo, rotation enhances substantially the dark matter density near the black hole. This thesis addresses the crossway of dark matter and galaxy development physics by modeling the faintest galaxies in deep space in a cosmological context. I explain a unified structure that incorporates dark matter restraints from dwarf galaxies and strong gravitational lensing, leading the way for next-generation surveys of small cosmic frameworks to supply unmatched understandings into dark matter physics. We study the effects of cold dark matter on the breeding of gravitational waves of primaeval and astrophysical beginning. We reveal that the dominant effect of cold dark matter on gravitational waves from astrophysical resources is a tiny frequency dependent modification of the breeding speed of gravitational waves. The wealth, circulation and inner structure of satellites of galaxy collections can be delicate probes of the properties of dark matter. Nonetheless, in this instance, the inner framework of subhalos are dramatically different in both dark matter models.

We present a self-interacting enhanced dark matter scenario as a feasible description of the lately reported extra of electron recoil occasions by the XENON1T experiment. While the visibility of the light vector boson arbitrator causes sufficient DM self-interactions to attend to the tiny range issues of chilly dark matter, the model with sub-GeV range DM can clarify the XENON1T unwanted using flexible spreading of improved DM component with electrons at the detector. We examine the application of machine learning methods for the detection of the astrometric signature of the dark matter base. We imitate the gravitational dynamics of an enormous item communicating with Ultralight/ Fuzzy Dark Matter, non-relativistic quantum matter described by the Schrodinger-Poisson formula. We generally verify straightforward estimates of dynamical friction timescales for a black hole at the center of a halo, yet see that a huge relocating factor mass delights meaningful breathing settings in a ULDM soliton. We think about a class of U^’ -extended MSSM in which the U^’ proportion is broken by a vacuum cleaner assumption values of 4 MSSM singlet areas. If the relic thickness of dark matter is filled just by a neutralino, compatible options anticipate LSP neutralinos formed by the MSSM singlet areas in the mass scales listed below regarding 600 GeV, while it is feasible to realize MSSM neutralino LSP above these mass scales. Previous studies have shown that dark matter deficient galaxies such as NGC1052-DF2 can result from tidal stripping. We present a unique mechanism of using solar neutrinos to speed up dark matter, motivated by the fact that neutrinos are one of the most energetic fragments of the Sun with a well-understood spectrum. In a neutrino portal dark sector model, we show that dark matter with sub-GeV mass could be sped up by the pp neutrinos to speeds well over 10^-3c and efficient in transferring huge sufficient energy at straight detection experiments.

In the same way as the awareness of a few of the renowned gedanken experiments thought of by the founding dads of quantum mechanics has lately led to the present renewal of the interpretation of quantum physics, it seems that one of the most recent progressions of empirical astrophysics can be analyzed as the awareness of some cosmological gedanken experiments such as the removal from the universe of the entire noticeable matter or the planetary time traveling resulting in a new cosmological conventional model. Whereas dark energy is typically connected with the cosmological continuous, we suggest clarifying dark matter as a pure QCD impact, particularly a gluonic Bose- Einstein condensate, complying with the change from the quark gluon plasma phase to the anemic hadronic phase. Abstract We carry out systematic research of the electrical and magnetic dipole moments of dark matter that are generated at the one-loop level when DM experiences four-fermion interactions with Standard Model charged fermions. We go over an examination of the dark matter decay modes of the neutron, proposed by Fornal and Grinstein, Berezhiani and Ivanov et al. We calculate the triple-differential random sample for the reaction e − + d → χ + p + e − and propose to look for such a dark matter network in coincidence with experiments on the electrodisintegration of the deuteron e − + d → n + p + e − right into neutrons n and protons close to threshold with outgoing electrons, protons, and neutrons in coincidence. The Gallbladder metagenome includes a wide variety of unidentified sequences comprising the so-called metagenomic dark matter. A series of reports over the last few years have shown that a much larger part of the animal genome is transcribed than can be accounted for by currently annotated genes, however the quantity and nature of these extra transcripts stays vague. The search for dark matter is just one of the most popular subjects in Physics today.
